By the end of October 2022, US HL-LHC Accelerator Upgrade Project (AUP) had completed fabrication ten MQXFA magnets and tested eight them. The are low beta quadrupole to be used in Q1 Q3 Inner Triplet elements High Luminosity LHC. This AUP effort is shared by BNL, Fermilab, LBNL, with strand verification tests at NHMFL. An important step QA plan testing a vertical cryostat BNL. acceptance criteria that could BNL were all met first four production (MQXFA03-MQXFA06). Subsequently, two (MQXFA07...
Fermilab (FNAL) and CERN have started the development of 11 T 11-m long Nb3Sn dipoles to replace a number LHC NbTi free space for cold collimators in DS areas. An important step design these magnets is high aspecept ratio cable achieve nominal field at operation current 11.8 kA 1.9 with 20% margin. Keystoned Cu wires RRP strand both mechanical stability minimal damage restack be used magnet short models. Each was characterized electrically transport properties degradation low feild...
The High-Luminosity LHC Accelerator Upgrade Project (AUP) in the U.S. will construct quadrupole magnets to be delivered CERN. An initial 3 tons, over 600 km total length of conductor was procured under R&D Program (LARP) for this project. Programs quality control(QC) at supplier and verification (QV) laboratories were solidified into components overall plan strand procurement AUP. Measurements critical current (Ic) residual resistance ratio (RRR), related probes techniques, are central...
The critical current density of brittle superconducting wires used in high field magnets is very sensitive to axial strain. An accurate measurement this strain dependence at various magnetic fields and temperatures for magnet design operation. A number methods techniques have been used, which generally fall into either the monotonic loading or bending spring techniques. a variable-temperature probe perform sensitivity measurements Helium both LTS HTS herein described. sample wound soldered...
The muon-to-electron conversion experiment (Mu2e) at Fermilab is designed to explore charged lepton flavor violation. It composed of three large superconducting solenoids: the production solenoid, transport solenoid (TS), and detector solenoid. TS formed by two magnets: upstream downstream. Each has its own cryostat power supply. Tolerance sensitivity studies position angular alignment each coil in this magnet system were performed past with objective demonstrate that design meets all field...
High-field superconducting magnets with a dipole field of 16 T and above enable future energy-frontier circular particle colliders. Although we believe these can be built, none exists today. They also showstopper for high-energy machines due to prohibitively high price tag based on the current conductor magnet fabrication cost. The high-temperature REBCO coated address both technical cost issues, silver bullet lay monsters rest. challenges unknowns, however, too arduous make bullet. We out...
The final beam cooling stages of a Muon Collider require DC solenoid magnets with magnetic fields 30-50 T. In this paper we present progress in insert coil development using commercially available YBa2Cu3O7.δ Coated Conductor. Technological aspects covered the development, including geometry, insulation, manufacturing process and testing are summarized discussed. Test results double pancake coils operated liquid nitrogen helium presented compared performance tape short samples.
The scope of the proposal outlined in this white paper is development and demonstration technology needed for next generation Nb_3Sn accelerator magnets 12-14 T range. main goal to cut magnet cold-mass cost by a factor 2 or higher with respect produced US Accelerator Upgrade Project (AUP) High-Luminosity Large Hadron Collider (HL-LHC). This will be achieved significant reduction labor hours, operating point, improved performance uniformity. A key automation that through industry involvement...
The magnet system of the Muon to electron (Mu2e) experiment at Fermilab consists three solenoid magnets: Production Solenoid (PS), Transport (TS), and Detector (DS). S-shaped TS contains 52 coils grouped into modules, which are typically 2 shrink fitted Al shells. These modules further units made 1-3 modules. As part acceptance process for these units, magnetic center all critical dimensions shells measured. model is updated with as-built values ensure requirements met. In addition, tested...
